Chapter 1: Prologue to the Chaos
Chapter Text
"Hahahahahahahahahahaha, you're too late, Perry the Platypus! Right now, my Multiversal-Villain-Summoner-Inator -- gosh I really need to get another name for that, it's quite a mouthful -- anyway, my latest invention has already activated! Now, the Tri-State Area will be MINE!"
If you guessed that this was the evil monologue of Dr. Heinz Doofenshmirtz, about to successfully complete his evil plan, you'd be correct.
On today's episode of Doofenshmirtz Evil Inc. , the good doctor had invented a machine -- sorry, inator -- that would summon villains from throughout the multiverse. Any villain could have showed up due to this, and I mean any villain, be it Vilgax, Thanos, Albert Wesker, Shao Kahn or even Darkseid. Now, if this invention were to succeed, the Tri-State Area was sure to be doomed.
"Wait, what are you doing? WAIT, PERRY THE PLATYPUS, DON'T! STOP! GET OUT OF THE MACHINE! NOOOOOOOOOOO!"
If you guessed that these were the words of Dr. Heinz Doofenshmirtz, having his grand scheme foiled, you'd be correct again!
You see, the way the inator worked was that one had to put themselves inside the machine, and the machine would summon beings from throughout the multiverse according to the characteristics that defined them the most. Since Doofenshmirtz thinks that evil is his most defining characteristic (it's not, him being a great father to his daughter is, but he doesn't know that), it's obvious what kind of people he wanted to summon.
However, as you could gather from his cries, his plans were, yet again, foiled by his arch nemesis, the blue-skinned, orange-beaked, fedora-wearing, Perry the Platypus, OWCA's own Agent P.
How did he foil the doctor's plan this time? Simple, he entered the inator himself.
And in doing so, unknowingly started the most chaotic crossover in existence.
KA-BLAMSKI! went the Multiversal-Villain-Summoner-Inator, and with it, the top of the roof of the Doofenshmirtz Evil Inc. building, kicking up a lot of dust and smoke. Perry avoided it all, while Dr. Doofenshmirtz got the brunt of it and was knocked onto the ground.
When everything settled, in the place of the inator, was a group of animals.
Namely, a cat, a mouse, 4 penguins, a duck, a bunny, and a raccoon.
All of them were confused. Scratch that, confused didn't even begin to describe how all of them were feeling.
Then the bunny took a look at the doctor on the ground, white lab coat now sporting a little bit of dust, and went, "Eeeeeeeh, what's up, doc?"
Chapter 2: Let the Chaos Begin!
Summary:
"I knew I shoulda taken that left turn at Albuquerque."
"Yes, because you going a different direction, would have stopped you from being summoned into an entirely new world!"
Notes:
Every dialogue I wrote, I imagined the characters themselves saying it. Makes it more fun to write!
Chapter Text
As is usual procedure when foiling Doofenshmirtz's evil plans, OWCA was contacted. What was not usual procedure was having to explain to the new group of animals, that they were in a new world.
"I knew I shoulda taken that left turn at Albuquerque." Bugs stated.
"Yes, because you going a different direction, would have stopped you from being summoned into an entirely new world!" his skeptical friend Daffy retorted.
"Hey, you don't know for sure it wouldn't have worked, now, Daffy! Don't be such a drowning duck."
"You call me a drowning duck one more time, and I'm having rabbit stew for dinner tonight!"
".......Daffy, you're a vegetarian." "IRRELEVANT!"
"So what you're saying is, I'm not only on Terra, but I'm on a Terra in a different universe?" Rocket said. "Well, that's just fricking great. Do ya have any bars here, at least?"
"Um, I don't think they'd serve raccoons," Carl nervously said, only to have an alien gun shoved in his face. "DON'T CALL ME A RACCOON!" Rocket bellowed. "The name's Rocket. Remember that." "Yes sir, Rocket sir!" came the panicked voice of Carl.
Major Monogram, meanwhile, was being interrogated by the Penguins. "So, you head a secret agency consisting of animal agents, huh? What do you call yourselves?" Skipper asked.
"We're called OWCA."
"What does it stand for?"
".......Organization Without a Cool Acronym."
You could hear the awkward silence. Major Monogram cringed more and more as the seconds of silence dragged on.
Skipper tutted, "Well that's just pathetic. Sounds like you need better management. And I happen to know just the penguin for the job. Kowalski! Come up with a better name once we take over these pansies. Rico! Salvage whatever you can from this mess, then when we get to our new headquarters, I'll need an inventory of all our equipment. And Private!"
"Yes, Skipper?"
"Do what you do best. Be yourself and win over our future agents."
"Aye aye, Skipper! I've already prepared gift baskets!"
"Thank you, Private. You are the most meaningful and valued member of this team." Even though Skipper had been saying this everyday for the past 2 years after they stopped Dave, these words never failed to bring a smile to Private's face and lift his spirits. "Thank you, Skipper."
"Always my pleasure, Private." Skipper told him softly. Then he turned to the Major. "Now you! Tell me more about my new agency's operational activities, Major Mustachio."
"It's Major Monogram, and it's not your agency, it's mine-"
"Whatever. Now, details. Or Rico's gonna paperclip them out of you." Rico hacked up a paperclip and had an eerie grin on his face. That convinced Major Monogram to, reluctantly, debrief his new boss.
After the debrief was done...
"Well, since we're gonna be stuck here for the time being, might as well get to know each other, huh?" Bugs said to the crowd of animals. "I'll start. My name's Bugs, and this scowling duck here is my best friend Daffy."
At this Daffy said, "We're associates at best."
"Don't let him fool you, he's just grumpy cause he hasn't had anything to eat yet."
"Well, I've been feeling the urge to cook some rabbit lately. And there's one conveniently right next to me."
"He also has a penchant for dark humor, so don't take him too seriously. Also, he's a vegetarian."
"Dark humor, huh? Sounds like my kind of person. Alright, I'll go next. My name's Rocket, I'm a bounty hunter in space."
"Ooh, a space bounty hunter! That must be a cool job!" Bugs exclaimed.
"It has it's perks." Rocket smirked.
Daffy then had a glint in his eye. He (not-so) sneakily whispered into Rocket's ear. "Say, how much would I have to pay you to get rid of that rabbit?"
Rocket scoffed. "Easy there, pal. I might start to like you, but you can't afford my prices."
"Oh, rats!"
"I'll go next. My name's Skipper, these are Kowalski, Rico and Private. We're an elite team. Best of the best. And, as of five minutes ago, we're also the new heads of an animal spy agency."
"Wow, you guys really must be the best if you managed that within five minutes. I might need to take some lessons from you so I can deal with Elmer better."
"Who is this Elmer?"
"Oh, just a silly human who wants to hunt me for sport. He's never succeeded ("unfortunately," Daffy muttered), but it becomes quite annoying when I want to sleep."
"Not to worry, my new achromatic friend. We'll train you so well, you'll be the one hunting him when you get back. Speaking of which. Rico! Did you salvage the blueprints of the machine that brought us here?"
"Ugh-huh!"
"Perfect. Kowalski, we'll need your expertise in reverse-engineering it."
"Yes, Skipper. I'll arrange for opposable thumbs when we get to base."
"That's what I like to hear. Alright, that's almost all of us. You two! The cat and mouse. What are your names?"
Tom and Jerry, who were too dazed to get up to their usual antics, shook away their stars and spoke, "I'm Tom!" "I'm Jerry!"
...
A pause.
Then,
""YOU TALKED!?!""
Tom spoke first. "Well sure I talk. What do you think I am, a dummy?" Jerry replied, "You said it, I didn't."
"Hey , you little pipsqueak, I oughta-" Tom paused in introspection. "Hey!" A pause again. "How come you never spoke before?!"
"Well there was nothing I wanted to say that I thought YOU'D understand, and there STILL isn't!" Jerry replied with vocal sass (as opposed to his usual brand of physical sass).
"Alright, that does it! You little-du-duoh-boy, you get me angry."
"Okay, doc, calm down. So you found out the other can talk, so what? We got more important things to worry about. Like, where are we gonna stay?" Bugs, strangely the voice of reason, cut in.
"Oh, we've got that handled, Bugs. We have a spy headquarters now, remember?" Skipper cleared his doubts. "The better question is, what do we do next?"
Meanwhile, in a suburban house in the Tri-State Area...
"Ferb, I know what we're gonna do today!"
Chapter 3: "Aren't you a little young to be causing this much chaos?" "Yes. Yes we are."
Summary:
The title speaks for itself! We now see how Phineas and Ferb contribute to the madness.
Notes:
A short one for this update, partly because I couldn't squeeze anything out of my muse, partly because of real life stuff.
(See the end of the chapter for more notes.)
Chapter Text
It was another day of summer vacation. Phineas and Ferb were lounging under the tree in their backyard, as usual. Then as usual, Phineas got up and exclaimed, "Ferb, I know what we're gonna do today!" Ferb, being used to this, simply turned his head.
"We're gonna try and build a multi-dimensional television!"
"That sounds rather ambitious." And it was rather ambitious. Trying to build a television system that could access the radio wave signals from various different dimensions was no easy task. The boys needed an absolute expert in quantum mechanics, quantum physics, quantum computing, quantum everything.
So naturally, Baljeet came over and solved it in 13 minutes, and helped assemble the blueprints. Buford took care of the hard labor, because he didn't want to miss out on the chance to see a "boxing-wrestling-football 3-in-1 match", in his words.
Not that there was any proof that such a thing existed, but hey, the multiverse is infinite. For all we know, in one world that could very well be the number one sport.
Once all the materials were gathered, the boys were busy setting everything up when Isabella showed up and asked, "Hey Phineas! Whatcha doing?"
Phineas looked at her and smiled, "Oh hey Isabella! We're building a multi-dimensional television!"
"Ooh, that sounds cool! Can I join?"
"Sure! Just put on the safety equipment over there."
Neither of them moved, still looking at each other and smiling until Ferb cleared his throat. Then the moment was broken and everything went on as per schedule.
Soon, the multi-dimensional television was all set up, and the gang were busy surfing through various channels they could access. There was one channel depicting a group of superheroes called the Justice League, saving the planet from alien invaders. "It seems strange that one of them dresses like a bat but has no connection power-wise to any bats whatsoever," Ferb commented.
Another channel showed the misadventures of a boy named Timmy who had fairy godparents that could grant him every wish. That channel became a favourite, along with the one where a group of friends and a talking dog, of all things, solved horror mysteries together. "What is the possibility that in another dimension, Perry could talk?" Baljeet asked. Phineas replied, "Well, it could be possible, but he's a platypus. They don't do much."
After a few more channel-surfing (wherein Buford was disappointed that there were no channels so far that showed any boxing-wrestling-football 3-in-1 matches) they finally landed on one where a coyote was chasing a roadrunner, and failing hilariously.
"Ha! If it was me, I'd have plucked that bird's feathers within 5 minutes!" Buford boasted. Baljeet cynically asked him, "Oh, and I suppose you could outrun a bird that has a top speed of 20 miles per hour, when you were huffing and puffing after running for 3 blocks?" Buford ignored it. "Man, that bird would look too dang funny with no feathers."
"Is it me? It is him, right?" Baljeet asked the others, who slowly nodded. Buford, now a little annoyed, shouted, "HEY! I can take on that stupid bird and beat it in a race! If it showed up right here, right now, it would eat my dust."
Of course, Fate couldn't help but answer that temptation. A flash of light later, and Buford was on the ground, while the others were pushed back a little bit, all coughing due to the dust that suddenly appeared. And when it cleared, in front of them stood the very bird they were watching on the television. It gave them a cursory glance, then leaned down to look at Buford in his eyes, as if he personally offended it in some way. Then, as if nothing had happened, it leaned back.
"Meep meep!" said Road Runner, before speeding off into the Tri-State Area.
Notes:
Be honest, you weren't expecting that, were you?
